ADJUSTABLE PILOT-LIGHT ATTACHMENT FOR GAS-FIXTURES.

Specification of Letters Patent.

Application filed June 17, 1908.

Patented Feb. 16, 1909.

Serial No. 439,061.

To all whom it may concern:

Be it known that I, GEORGE Grrcnnn, a citizen of the United States ofAmerica, and a resident of Ridgefield Park, New Jersey, have invented anew and useful Improvement in Adjustable Pilot-Light Attachments forGas-Fixtures, which improvement is fully set forth in the followingspecification.

This invention relates to gas-cocks where it is desired to maintain whatis known as a pilot-light. In such contrivances the gas can be turnedfully on, yet when the cock is turned the other way, the gas can not beout completely off, since a small jet continues to burn as a pilot-lightso-called.

My invention consists of a device suitably constructed and arrangedwhereby either the gas may be turned low to produce such pilotlight(without any chance of turning it out entirely), or, at will, by asimple manipulation of my device, the gas may be turned oif entirely.

The invention will be best understood by reference to the annexeddrawings in which- Figure 1 is a side elevation illustrating oneembodiment of myinvention affixed to a gascock; and Fig. 2 is a bottomview ofthe same; while Fig. 3 is a transverse section of a detachabledevice adapted for connection with gasiixtures already in use.

1-1 represents the ordinary gas-pipe; and 2 the key or handle of thegas-cock having the usual transversely-apertured barrel 3 that turns inthe hollow barrel 4, which latter is really part of the gas-pipe 1-1.Upon the barrel 3 is a stud 5 whichwill abut against either one ofthetwo oppositely-located stops or shoulders 6 formed by cutting away aportion of the barrel 4,-all of which is the ordinary construction nowin use.

According to the present invention, I employ a device such as 7 that maybe interposed in front of the shoulders 6, so as to intercept the stud5, to limit the extent of its axial play, and thereby prevent the gasbeing turned completely off and this device 7 may at will be moved outof the way, so that the stud 5 may be turned all the way back to eithershoulder 6, and thus cut the gas completely oif. When the device 7 is inoperative position, I have a pilot-light device; when the device ismoved into inoperative position, I have an ordinary gas-cock. Accordingto my preferred construction, this device 7 is shown as shaped ingeneral like the letter Y, with its branches constituting substantiallya semicircle, and its stem serving as a thumb-piece or handle. At thecenter it is pivoted to a bearing upon the gaspipe, this bearing beingeither made integral with the gas-fixture or secured thereto. Thedrawings indicatethis device 7 as pivoted by means of a pin 8 secured bya nut 9 through a plurality of registering bearings 1() and l1 upon thegps-pipe and the device 7, res ectively. T e thumb-piece 12 serves -W enpressed against the gas-pipe to move the device out of operativerelation with the stud 5. By properly adjusting the nut 9 once for all,sufficient tension is obtained to cause the pivoted device 7 to remainin whatever position it may be placed. When the device 7 is moved intooperative relation, and the key 2 is turned as for cutting off the gas,then the stud 5 will abut against one of the two ends 13 (or 13') of thedevice, so that the gas can not be turned completely off. Set-screws 14in the ends of the device 7 may be utilized as adjustable stops for thestud 5, so as to vary the extent to which the key 2 may be turned, andthus vary the amount of gas left for the pilot-light.

In Fig. 3 is shown a clip (or other suitable device) 15, to which thedevice 7 is pivotally secured by the pin 8, which passes throughbearings 10 ofthe clip and bearings 11 of the device 7. This clip may besecured in place on a gas-fixture by a clamping-screw 16 or otherwise.This construction may be manufactured in assorted sizes as a stockarticle, and employed interchangeably upon ordinary gas-fixtures.

I have explained my invention with some detail, but only for the sake ofclearness. Parts of my invention may be used to the exclusion of otherparts, and changes may be made in the details of construction andarrangement and additional features may be employed therewith, withoutdeparting from the spirit of my invention.

Having thus described my invention, I claim:

1. The combination with a gas -iixture comprising a gas-cock havingmeans to limit its play, of a substantially Y-shaped device carrying aset-screw in the end of each branch and movable into and out ofoperative relation to said gas-cock to still further limit its play.

2. The combination with a gas-fixture comprising a key having a studthereon and shoulders against which said stud abuts to 20 cock of saidgas-fixture.

limit its play, of a substantially Y-shaped device pivotally mountedupon said fixture and with its ends movable into and out of positionbetween said stud and the shoulders.

8. The combination with a gas-fixture comprising a key having a studthereon and shoulders against which it abuts to limit its play, of asubstantially Y-shaped device pivotally mounted upon said fixture andmovable into and out of position in Jfront of said stud, and set-screwsprojecting from thedends of said device to abut against said stu 4. Asan article of manufacture, the herein described interchangeablepilot-light device, comprising a substantially Y-shaped member, andmeans for securing it pivotally to a gas-iiXture so that its ends may bemoved into position to limit the play of the key or 5. As an article ofmanufacture, the herein-described interchangeable pilot-light device,consisting of a clip or the like adapted to be secured t-o agas-fixture, and a substantially Y-shaped device pivotally mounted up onsaid clip, as and for the purpose described.

6. A clip or the like adapted to be se-y cured to a gas-fixture, and adevice pivot- GEORGE GJLCHER. f
